In a large saucepan, rinse fruit. Combine fruit and water; simmer over medium heat about 10 minutes. Drain; stir in sugar. Blend cornstarch and cold water into a smooth paste. Add cornstarch to fruit, stirring constantly. Bring mixture to a boil; cook 3 minutes. Remove from heat and stir in vanilla. Sieve mixture, if desired. Chill. Serve with cream and decorate with blanched almonds, if desired.
